com BOX roe TELEPHONES.

Application filed February a, 1922. serial no. 535,883.

To all whom it may concern:

Be it known that I, AXEL G. SANDBERG,

a citizen of the United States, residing at Worcester, in the county of Worcester and a State of Massachusetts, have invented a new and useful Coin Box for Telephones, of which the following is a specification.

This invention relates to a box for use in reminding telephone users of the fact that to telephone calls have to be paid for and at the same time for receiving the coins deposited for that purpose.

The principal object of the invention is to provide a device having the above mentioned characteristics which will be very inexpensive to make and maintain and will not involve any unnecesary or expensive features.

The invention also involves a novel way of mounting the parts of a coin box and at the same time connecting them together, and

a simple and convenient way of providing for the detachment of the cover to permit access to the bottom of the box.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which- Fig. 1 is a side elevation of a coin recep tacle constructed in accordance with this invention showing in dotted lines a telephone instrument to which it may be attached;

Fig. 2 is an elevation of the device looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a side view of the cover; Fig. 4 is a side view of the attaching bracket;

Fig. 5 is a similar view of the bottom of to the box;

Fig. 6 is a plan of the box;

Fig. 7 is a plan of the bracket; and

Fig. 8 is a central verticalsectional view of the box assembled.

I have shown the coin box itself as consisting of a bottom 10 and a top 11. These two parts can be made of substantially the same shape so that they can be pressed up of sheet metal in the same set of dies, but the top is provided with a slot 12 for receiving the coins which, of course, is not presan and 11 are formed of a general cylinctnical form with a fiat end and the other end open.

in the bottom. Both of these parts 10 The open ends are flared out at the edges to form a circumferential projection 13 having the cross section of. a quarter circle.

each other to form two arms 21 close to each other, which can be securely attached together by screws or bolts 22. These arms are bent outwardly to form two semi-circular parts 23, together forming a collar for surrounding the neck of the telephone instrument to which it is to be applied, and the ends are brought together at 24 to receive another bolt or screw 25 to fasten these parts.

In the formation of the circular collar 20 it is bent outwardly at the center to form a circumferential rib 26. The inside of this rib, which constitutes a circumferential groove, is arranged to receive the two circumferential projections 13 when the two parts 10 and 11 are assembled with their flaring edges in contact with each other.

When'the bolts or screws 22 and 25 are tightened the two parts of the coin box are not only secured together but are securely mounted on the telephone instrument.

When it is desired to empty the box, the screws are loosened sufiiciently to permit the detachment of the cover 11. In doing this the plate 14: can be used as a handle for manipulating it. The bottom 10 cannot be removed as it is provided with a series. of outwardly extending nicks or projections 29 which extend into corresponding depressions in the inside of the collar 20.

When the cover 11 is removed the fingerS can be inserted in the box 10 to remove the coins or the whole instrument can be turned upside down to empt them.

From this descriptlon it will be obvious that a very inexpensive device for the purpose intended is thus provided and that it will serve to hold any desired number of coins in accordance with its dimensions, and

also serve to remind the telephone users that they ought to pa for the service without necessitating any urther reminder.

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any fperson skilled in the art without departing rom the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is 1. As an article of manufacture, a telephone coin box comprising a substantially identical bottom and top closed at their opposite ends and open at their adjacent ends which flare outwardly and are in contact with eac other, a sheet metal collar surrounding said adjacent ends and having a circumferential groove inside for receiving both flaring open ends of the box and cover, said collar having its two ends projecting from it radially and close together and having opposite semi-circular bends forming a space for receiving a part of a telephone instrument, and means for clam ing said ends together to secure the collar a out the box and to secure it to a telephone instrument.

2. As an article of manufacture, a telephone coin box comprising an upper and lower portion having flaring openings at their adjacent ends adapted to be brought into registration with each other, and a collar provided with a circumferential rib thereon providing a similar groove inside for receiving said flaring ends, and provided with means for clamping said collar on the adjacent ends of the box to hold them in position with respect to each other, said bottom being permanently connected with said collar whereby it will support the top when the collar is loosened, and the top being removable and the top having a projection extending therefrom constituting a handle,

In testimony whereof I have hereunto affixed my signature.

AXEL Gr. SANDBERG.
